noLoop() turns off smoothing

This may have an obvious answer, but it's escaping me:

The following simple program will generate a smooth ellipse with noLoop() and a rough one without it. It's as if the smooth() command has no effect if the draw() function is looping:

void setup() {
size(300, 300);
noStroke();
smooth();
noLoop();
}

void draw() {
ellipse(width/2, height/2, 50, 50);
}

Very strange. I have been having this issue for a while, and persists even with the 1.0 release of this week. This is on a Mac by the way.

When I run this code in a new Processing installation on Ubuntu (running in a VM on my Macbook Pro) I get the same effect: noLoop() retains smoothing, and without it, I loose smoothing.

I am stumped!
